Why DevOps ?
Development Vs Operations: Break
down barriers enabling
• Trust and shared ownership
• Encouraging collaboration
• Accelerating innovation.
• Simplify & advocate “Agility” across the
application lifecycle management
• Measurable business benefits through
integratable IT Process Management
o According to Forrester, As IT organizations struggle to deal with the
changing IT and business landscapes, the concept of DevOps
(development + operations = DevOps) has been singled out by many
as the way in which infrastructure and operations (I&O) can better work
with other IT silos to benefit the business. Getting DevOps right will
address many of the issues enterprises consistently have with IT, such
as applications failing to meet both functional and nonfunctional
requirements, delivery delays, increased costs, and an inflexibility to
change. Success will require mastering six steps
▪ Change your change management.
▪ Communicate more often with the app dev group to increase its
knowledge about Operations.
▪ Consider app dev as “service dev.”
▪ Understand and manage the diversity of views on IT delivery.
▪ Integrate I&O’s mission statement with the business.
